System battery
The server uses volatile memory that requires a battery to retain system information when power is removed. This
3-volt lithium coin cell battery is located on the system board.

If the server no longer automatically displays the correct date and time, you may need to replace the system
battery. Under normal use, battery life is five to ten years.
WARNING! Note the following reminders when replacing the system battery:
•
Replace the battery with the same type as the battery recommended by HP. Use of another battery may present a risk of
fire or explosion.
• A risk of fire and chemical burn exists if the battery is not handled properly. Do not disassemble, crush, puncture, or
short external contacts, or expose the battery to temperatures higher than 60°C (140°F).
• Do not dispose of used battery in water or fire. Dispose of used batteries according to the manufacturer's instructions.
CAUTION: Loss of BIOS settings occurs when the battery is removed. You must reconfigure BIOS settings
whenever you replace the battery.
To replace the system battery:
1. Perform steps 1 through 3 of the Pre-installation instructions.
2. Remove the access panel.
3. Lay the server on its side for better access to the battery holder (XBT2).
4. If necessary, remove any accessory boards or cables that prevent access to the battery holder.
